Nina Agdal has spoken out after claiming she was body-shamed by a magazine who decided against running her cover story because she did not fit into their sample size.

The defiant supermodel, 25, released an image from the shoot on her social media page, claiming the picture of her posing topless in a pair of jeans was rejected because the publisher said it "deviated from her portfolio" and "did not fit their market."

In an open letter to the fashion and publishing industry, the Danish model said she embraced her curves, refused to apologise for them and wasn't built to be 'stick thin.'

"If anyone has any interest in me, they know I am not an average model body - I have an athletic build and healthy curves," she fired.

Nina, whose modelling credits include Vogue, Maxim and the coveted Sports Illustrated Swimwear edition continued : "After a tough year of taking a step back from the insensitive and unrealistic pressures of this industry and dealing with paralyzing social anxiety, I walked into that shoot as a 25 year old WOMAN feeling more comfortable in my own skin and healthier than ever before.

"Some days I'm a sample size, some days I'm a size 4 and some a 6."
